Which statement made by a patient who has acute pyelonephritis indicates to the nurse correct understanding of the antibiotic therapy?

Choice A reason: Doubling the dose of antibiotics is unsafe and can lead to toxicity. Dosage adjustments should only be made by a healthcare provider. Choice B reason: Mild diarrhea is a common side effect of antibiotics. While severe diarrhea may warrant evaluation for Clostridioides difficile infection, routine diarrhea does not require an automatic change in medication. Choice C reason: Completing the full course of antibiotics is essential to ensure eradication of the infection and prevent resistance, even if symptoms resolve early. Choice D reason: Normal temperature does not confirm complete resolution of infection. Stopping antibiotics prematurely can lead to recurrence or resistance.
